This bill mandates the Department of Transportation to install sound barriers along specific segments of the F.E. Everett Turnpike in Merrimack, New Hampshire. The sound barriers will be constructed on the west side of the turnpike southbound, southwest of Interchange 12, covering neighborhoods such as Roundtree Drive, Davis Road, Vista Way, Ministerial Drive, Weston Road, and Kittridge Lane. Additionally, barriers will be erected on the west side of the turnpike southbound, northwest of Interchange 12, including areas like Back River Road, Bradford Drive, Belmont Drive, Raymond Drive, Small Lane, and Brookfield Drive. The bill states that it will take effect upon passage.

The estimated cost for the installation of these sound barriers is approximately $7,200,000, which will be funded through the Turnpike Fund. The bill does not provide specific funding but outlines the expected expenditures for the project, with the Roundtree Drive neighborhood barrier estimated at around $3,300,000 and the Back River Road barrier at approximately $3,900,000. The bill does not include any deletions or modifications to existing law, focusing solely on the new requirement for sound barrier installation.
